2016-01-15

A new project developed by the microcapsule research and development team of Jiangxi Weilbao Food Biology Co., Ltd. has been patented. A process for preparing microencapsulated wall materials of fat-soluble substances with starch as raw material has been authorized. A process for preparing microencapsulated wall materials of fat-soluble substances with starch as raw material has been used. By controlling the starch moisture under negative pressure, the crystallization degree of starch is partially destroyed by direct heating, and octenyl succinic anhydride is used as esterification agent, after washing and centrifuging, the post-treatment of octenyl succinic acid starch ester was carried out by spray drying and boiling furnace thermal conversion process, and the fat-soluble core material microencapsulated starch ester wall material was prepared. The invention has novel production process, simple operation, easy control of production parameters, convenient continuous industrial production, stable product, low production cost and low pollution.
